FORMING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 555,575, dated March 3,1896.

Application filed May 18, 1895. Serial No. 549,746. (No model.)

To all whom it may concern.-

Be it known that we, J UDSON N. LAKE and JASPER CLARK, of Elmira, in thecounty of in the State of New York, have invented new and usefulImprovements in Forming-Machines, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to improvements in forming-machines upon whichLetters Patent of the United States were grantedto Jasper Clark, datedMay 28, 1895, No. 539,856, having more particular reference to themechanism for soldering the laps or joints of the cylinder.

Our object isto produce a mechanism to be applied to forming-machinesfor easily, efficiently, and cheaply soldering or uniting the sides ofthe cylinder or meeting edges of the receptacle; and to that end ourinvention consists in the several new and novel features andcombinations of parts hereinafter described and which are specificallyset forth in the claim hereunto annexed. It is constructed as follows,reference being had to the accompanying drawings, in which Figure 1 is aside view of a forming-machine provided with our improvements. Fig. 2 isan enlarged view of the grooving apparatus. Figs. 3 and at are edge andside views, respectively, of the grooving-wheel. Fig. 5 is a top planview of the mandrel. Fig. 6 is an end View thereof. Fig. 7 is across-section of a segment of the mandrel, showing the lap of themeeting edges of the cylinder. Fig. 8 is a similar view showing themgrooved ready for the solder.

A is the frame constructed in any ordinary manner.

B is a mandrel having a longitudinal groove a, preferably upon its upperface, and is vertically yieldingly mounted, as set forth in theapplication above referred to, and means are provided for clamping themetal a around the mandrel, said meeting edges overlapping each othersubstantially as shown at b in Fig. 7, one of the edges being within theline of the groove a.

c is a treadle suitably mounted and is connected to the frame in whichthe mandrel is mounted by rods 0, so that when the treadle is depressedto the position shown in Fig. 1 in dotted lines the mandrel will takethe position shown in dotted lines in the same figure.

Upon the rear of the frame A is mounted a bracket 0, comprising anupright d and rearwardly-extending arm d. Upon the bracket 0 isslidingly mounted an arm D, one end of which is provided with a roller6, which allows it to move longitudinally upon the arm of the bracket62. In the opposite end is journaled the grooving-wheel E, constructedsubstantially as shown, and above the arm D is a frictional roller 6yieldingly mounted and adapted to engage with the upper edge of said armD.

f is an operatinghandle secured to the arm D. p

hen the metal has been clamped around the mandrel so that the meetingedges overlap each other, as above described, and the mandrel broughtdown to the position shown in dotted lines in Fig. 1, the grooving-wheelE will be in line with the groove a upon the mandrel. e then force thearm D over and allow the grooving-wheel E to force the lap into thegroove, as shown in Fig. 8, thereby forming what we are pleased to callagrooved lap g. \Ve then pour metal into the groove thus formed, therebysoldering the meeting edges together.

Having described our invention, what we claim, and desire to secure byLetters Patent, 1s

In a formingmachine, the frame, a Vertically-movable grooved mandrelmounted thereon, means for moving the mandrel, and a bracket projectingfrom one end of the frame, combined with a sliding arm mounted on thebracket, a handle attached to the top of the arm and extending towardthe mandrel, the grooving-wheel E journaled upon the inner end of thearm, and the frictional wheel 6' mounted upon the frame and bearing uponthe top edge of the arm, substantially as shown.

In witness whereof we have hereunto set our hands on this 20th day ofApril, 1895.

JUDSON N. LAKE. JASPER CLARK. In presence of JAMEs M. MooKLER, EDWARD A.PRENTICE.
